Investigation of Acceptable Levels of Li-ion Battery Deterioration in Different Electric-driven Vehicle Types

Abstract

This paper discusses the levels of deterioration in Li-ion batteries that are acceptable in different types of electric-driven vehicles. Simulation-based analysis of the adverse effects of battery deterioration on vehicle performance was carried out, and acceptable degrees of battery deterioration are proposed based on the criteria of 20% loss of performance (20% reduction in cruising range for BEVs, 20% increase in fuel consumption for HEVs and 20% increase in CO₂ emissions for PHEVs).
